Open up the checkbook, pay whatever you need to crank a song.
Promotion is billed back to the artist.
The song becomes a hit, let’s say sells 1-2 mm.
750 – 1.5 million in revenue.
Artist is more than likely unrecouped anyway.
So just mechanicals have to be doled out.
Then, because the song is a hit, more views on YouTube (adrev), more streams on Pandora, Spotify, etc. (adrev).
So the income stream multiplies.
Hence the new kamikaze promotion spends.
150-300k out, a million plus in.
No indie label on Earth can compete with the money being thrown around out there today.
